Actually it is:

http://www.postgresql.org/docs/9.4/interactive/locale.html

"Locale support refers to an application respecting cultural preferences
regarding alphabets, sorting, number formatting, etc. PostgreSQL uses
the standard ISO C and POSIX locale facilities provided by the server
operating system. For additional information refer to the documentation
of your system."

The reason I ask is that the machine you are having problems with has OS
X. Over the years I have seen quite a few reports on this list of OS X
locale/encoding issues.

I get this also via JDBC.
